Hi Shailabh, Took a look at your documentation on using the I/O controller. I can see how one might use the I/O controller if one had a few classes. E.g., the gold, silver, and bronze class of I/O based processes (or maybe up to ~20 classes). However, in my environment I may potentially have hundreds of vservers. What I was hoping for was a means to isolate one vserver's I/O bandwidth consumption from that of other vserver. I.e., something more like a proportional share of the I/O bandwidth. For this reason, I was expecting that I could create a one-to-one mapping between each vserver and a new class and give each vserver a share. It is not obvious to me how I would do that using your scheme.
Of course, it is entirely possible that I simply misunderstood the way one can use the I/O controller. In what way do you suggest I assign I/O shares to each of these vservers?

On my P4 SMT box, I'm able to run tiobench's in different classes though I don't observe a significant differentiation between the priority levels. OTOH, the depth of the I/O request queues formed by tiobench is pretty small so that needs to be eliminated as a cause by using an aio-based test. Please give it a spin. There's rudimentary documentation included in the patch. Marc, I'm getting onto the differentiation resolution now. Let me know if this controller creates problems like last time...
